this study examined suitable mechanized methods to seed rice in dry-bed conditions using dried seeds and determined the most suitable varieties for each method. the experimental design was strip-plots in a randomized complete block design with two factors (seeding methods and rice varieties) and three replications. the testing took place during 2003-2004 at the shavour agricultural research sta...

To help farmers in the mid hills of Nepal improve their crop management and rice yields, we conducted a study testing different nursery management options and their effect on grain yield and yield components under rainfed conditions. The experiment was conducted in a farmer’s field during the cropping season 2009 and 2010 at Sundarbazar, Lamjung, Nepal, using a 3-factor factorial RCB design wit...

A procedure for surface hydrolysis of poly(glycolic acid) (PGA) meshes was developed to increase cell seeding density and improve attachment of vascular smooth muscle cells. Hydrolysis of PGA in 1N NaOH transformed ester groups on the surface of PGA fibers to carboxylic acid and hydroxyl groups. After hydrolysis, the polymer scaffold retained its original gross appearance and dimensions while t...

Seed availability and leaf litter limit plant establishment in some ecosystems. To evaluate the hypothesis that these factors limit understory plant recruitment in Pinus ponderosa forests, I conducted a seeding and litter removal experiment at six thinned sites in the Fort Valley Experimental Forest, northern Arizona. Experimental seeding of four native species (Penstemon virgatus, Erigeron for...

Since the mid-1980s, sagebrush rangelands in the Great Basin of the United States have experienced more frequent and larger wildfires. These fires affect livestock forage, the sagebrush/grasses/forbs mosaic that is important for many wildlife species (e.g., the greater sage grouse (Centrocercus urophasianus)), post-fire flammability and fire frequency. When a sagebrush, especially a Wyoming big...

Adult mesenchymal stem cells (MSCs) are being investigated further for their use in stem cell therapies. However, as they are found in very low numbers in adult tissue, expansion in vitro is required to produce desired MSC numbers for clinical application. The need for effective cell-based therapies is increasing due to a rise in the ageing population, increasing the prevalence of musculoskelet...

background: despite major progress in our general knowledge related to the application of adult stem cells, finding alternative sources for bone marrow mesenchymal stem cells (mscs) has remained to be challenged. in this study successful isolation, multilineage differentiation, and proliferation potentials of sheep mscs derived from bone marrow, adipose tissue, and liver were widely investigate...

The objective of this study was to identify a combination of growth factors that could be used with hydrostatic pressure (HP) stimulation to enhance the functional development of cartilaginous grafts engineered using human infrapatellar fat pad derived stem cells (FPSCs) isolated from osteoarthritic patients. Agarose hydrogels were first seeded with FPSCs at different seeding densities and main...
